Dynamic force behavior for linear guideways with balls of different materials
The feed drive system for the machine tool consists of rolling elements such as ball screws and linear guides. It is well known that in the positioning of linear guideways using a ball rolling, the behavior has nonlinear spring characteristics. The nonlinear spring characteristics will change if you...

The feed drive system for the machine tool consists of rolling elements such as ball screws and linear guides. It is well known that in the positioning of linear guideways using a ball rolling, the behavior has nonlinear spring characteristics. The nonlinear spring characteristics will change if you change the type of the linear guide or feed amount. In this study, we have manufactured a feed drive system in which the physical contacts are only linear guideways by using a linear motor as an actuator. First, it was confirmed by step input that the time constants were sufficiently equal. Next, in the brush model, a large displacement step is input to create a state in which all brushes were bent. The same experiment was performed by inputting a sine wave from there and changing the linear guideway. This paper presents the changes in the spring characteristics depending on the material of the balls by considering the response to linear guideways used in different ball materials. |
